Note: CFI = Comparative Fit Index. NNFI = Non-normed Fit Index. SRMR = Standardized root mean-square residual. RMSEA = Root mean-square error of approximation. Df: Degree of freedom. FL: Factor loadings constrained to equality across boys and girls. FL and Cov: Factor loading and covariance constrained to equality across boys and girls. Cov (PAS, CAS): covariance between parent anxiety sensitivity and child anxiety sensitivity. Cov (CAS, pain): covariance between child anxiety sensitivity and pain.
